Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction equipment, and in particular to an arch-anchor-grouting combined operation trolley and a construction method. Background Art

[0002] The arch anchor trolley in tunnel construction is a mechanical equipment specially designed for tunnel support. It is mainly used for initial support after tunnel excavation, especially under soft surrounding rock conditions. It can quickly and effectively complete tasks such as arch frame installation, anchor construction and grouting. The design of the arch anchor trolley integrates multiple functions, which can significantly improve construction efficiency while ensuring the safety of workers. However, most of the existing arch anchor trolleys for tunnel construction are special vehicles. In actual use, the arch anchor trolley often needs to be fixed in the same position for a long time. At the same time, the transportation of materials required for construction requires the purchase of additional special material transfer vehicles, which undoubtedly increases the cost of the project.

[0003] In addition, most of the existing arch anchor trolley construction operations use two clamping cylinders to drive two clamping claw mechanisms, which has a complex control method and high cost.

[0004] Most existing arch anchor trolleys do not have the grouting function. When performing grouting operations, the mixing station outside the tunnel is connected to the working surface through a pipeline, and the slurry is provided by the external mixing station; or the mixing equipment is directly moved into the tunnel. As the tunnel construction work progresses, the mixing equipment also needs to be continuously moved forward. These two methods have many inconveniences in actual operation. Since the ground conditions are often not flat enough during tunnel construction, each time the mixing equipment is moved, it takes extra time to place and level it, which not only increases the complexity of the operation, but also seriously slows down the construction progress, resulting in a significant reduction in overall operation efficiency. Therefore, the development of a multifunctional arch anchor trolley that can integrate mixing and grouting functions can not only solve the above problems, but also further improve construction efficiency and safety.

[0005] A Chinese patent (publication number: CN217925939U) discloses an arch anchor trolley with a grouting function; the patent provides an inwardly recessed groove area on the side of the vehicle body, a grouting machine is embedded in the groove area, and the grouting machine is connected to the vehicle body through a lifting assembly; but the patent is also for a special vehicle, and the transportation of materials required for construction requires the purchase of a special material transfer vehicle; in actual use, it was found that since the grouting machine was embedded in the side of the vehicle body, it was not convenient for feeding operations and was inconvenient to use.

DETAILED DESCRIPTION

[0042] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0043] Embodiment 1, in combination with Figures 1 to 4 A combined arch-anchor-grouting operation trolley comprises a trailer body 1 and a boom system 5 for construction operations, and also comprises an operation platform 2 and a stirring grouting device 3.

[0044] The trailer body 1 is provided with a chassis structure that can be separated from the bottom of the working platform 2. Figure 1 As shown, the four corners of the working platform 2 are provided with hydraulic legs 4 for lifting and supporting the working platform 2. When the working platform 2 needs to be separated from the trailer body 1, the stirring grouting device 3 is first pulled out from the bottom of the working platform 2 so that the stirring grouting device 3 avoids the wheels of the trailer body 1; then the working platform 2 is lifted and supported by the four hydraulic legs 4, so that the working platform 2 can be separated from the trailer body 1. The operator can use the trailer body 1 to transport the materials needed for tunnel construction, and the vehicle can be used for two purposes, which improves the practicality.

[0045] Combination mechanism of trailer body 1 and working platform 2:

[0046] The chassis structure includes a support frame 1-1 that is fastened to the top of the beam of the trailer body 1, and a support plate 1-3 for supporting the working platform 2 is provided above the support frame 1-1. The support plate 1-3 is slidably connected to the support frame 1-1 left and right through a sliding mechanism. A guide groove 1-9 is provided on the top of the support plate 1-3, and a plurality of guide posts 1-10 that can slide and cooperate with the groove wall of the guide groove 1-9 are provided at the bottom of the working platform 2. Through the cooperation of the guide posts 1-10 and the guide grooves 1-9, the operator is guided to drive the trailer body 1 into the bottom of the working platform 2, so that the support plate 1-3 can overlap with the working platform 2, so as to facilitate the alignment of the central axis of the working platform 2 with the central axis of the trailer body 1, and avoid the deviation of the center of gravity of the trailer body 1.

[0047] In order to reduce the difficulty of operation when the trailer body 1 is combined with the working platform 2, two guide pillars 1-10 are arranged at the bottom of the working platform 2, which are respectively located at the two ends of the bottom of the working platform 2.

[0048] In order to avoid serious hard friction between the guide post 1-10 and the groove wall of the guide groove 1-9 when the trailer body 1 is combined with the working platform 2, the column body of the guide post 1-10 is rotatably connected with the roller 1-11, as shown in the attached Fig.11 In this way, when the trailer body 1 drives the support plate 1-3 to enter the bottom of the working platform 2, the roller 1-11 rolls along the groove wall of the guide groove 1-9, effectively reducing the friction between the guide column 1-10 and the groove wall of the guide groove 1-9.

[0049] When the working platform 2 needs to be transported by the trailer body 1, the operator can drive the trailer body 1 to the bottom of the working platform 2. Before the trailer body 1 enters the bottom of the working platform 2, the guide groove 1-9 needs to be aligned with the guide post 1-10. The end of the guide groove 1-9 corresponding to the rear of the trailer body 1 is in a trumpet-shaped structure, which facilitates the guide post 1-10 to smoothly enter the guide groove 1-9.

[0050] During the process of the trailer body 1 entering the bottom of the working platform 2, if the longitudinal axis of the guide groove 1-9 is not parallel to the longitudinal axis of the working platform 2, the second guide post 1-10 cannot enter the guide groove 1-9. At this time, the operator only needs to adjust the driving direction of the trailer body 1, and the support plate 1-3 can adaptively move left and right under the action of the sliding mechanism, which on the one hand avoids applying a large lateral force to the working platform 2, and on the other hand avoids the operator from having to drive the trailer body 1 out of the working platform 2 multiple times to adjust the direction of the trailer body 1, effectively reducing the difficulty of operation when the trailer body 1 is combined with the working platform 2, and improving the operating efficiency.

[0051] It should be noted that before the trailer body 1 enters the bottom of the working platform 2, it is necessary to adjust the height of the working platform 2 through the hydraulic legs 4 so that the bottom of the working platform 2 is higher than the top surface of the support plate 1-3, and the bottom end of the guide column 1-10 is located in the guide groove 1-9 to prevent the guide column 1-10 from slipping out of the guide groove 1-9 and losing its guiding function.

[0052] Combined with Figure 3 and 4 The sliding mechanism includes a support beam 1-2 disposed at the top of the support frame 1-1, and a gap is left between the top of the support beam 1-2 and the bottom of the support plate 1-3. The support beam 1-2 is movably connected with a plurality of guide rods 1-4 at intervals, and the two ends of the guide rods 1-4 are respectively fastened to the bottom of the working platform 2 through the connecting plates 1-5. The guide rods 1-4 are provided with springs 1-6 corresponding to the rod bodies between the support beam 1-2 and the connecting plates 1-5. When the connecting plate 1-5 is not subjected to external force, the connecting plate 1-5 can automatically align with the support frame 1-1 left and right under the action of the spring 1-6. When the guide column 1-10 applies lateral force to the connecting plate 1-5, the connecting plate 1-5 can move left and right along the axial direction of the guide rod 1-4 and the support frame 1-1.

[0053] A plurality of support wheels 1-7 that are in rolling contact with the support frame 1-1 are arranged at intervals on both sides of the beam body of the support beam 1-2 at the bottom of the support plate 1-3. The support plate 1-3 can directly apply its own gravity and bearing capacity to the support frame 1-1 through the support wheels 1-7 to prevent the guide rod 1-4 from bending due to a large bending moment.

[0054] A telescopic rod 1-8 is installed between the support beam 1-2 and the support plate 1-3 to align the support plate 1-3 with the support frame 1-1. When the support plate 1-3 overlaps with the working platform 2, there may be a left-right misalignment between the support plate 1-3 and the support frame 1-1. At this time, the hydraulic support legs 4 are controlled to shorten so that the working platform 2 falls on the support plate 1-3, and the hydraulic support legs 4 are ensured to be completely off the ground. The support plate 1-3 is driven to move along the guide rod 1-4 by the telescopic rod 1-8 until the support plate 1-3 overlaps with the support frame 1-1, ensuring that the central axis of the working platform 2 is aligned with the central axis of the trailer body 1.

[0055] It should be noted that, when the trailer body 1 enters the bottom of the working platform 2, the telescopic rod 1-8 needs to be kept in a freely telescopic state to avoid interference with the adaptive movement of the support plate 1-3.

[0056] The positions of the support frame 1-1 and the support plate 1-3 corresponding to the stirring grouting device 3 are both provided with a clearance notch, as shown in the attached Figure 1 and 2 When the working platform 2 is transported, the stirring and grouting device 3 can be pushed into the bottom of the working platform 2, and the stirring and grouting device 3 can enter the clearance area, thereby reducing the overall width, making it easier for the operator to drive the trailer body 1 through the narrow area.

[0057] The structure and working principle of the stirring grouting device 3:

[0058] As attached Figure 5 As shown, a stirring grouting device 3 for grouting operation is provided at the bottom of one side of the working platform 2 corresponding to the position between the front and rear wheels of the trailer body 1. The stirring grouting device 3 can be integrated on the working platform 2, which is convenient for grouting operation during tunnel construction, and does not occupy the working space on the working platform 2, and does not affect the normal operation of other working equipment on the working platform 2.

[0059] The stirring grouting device 3 includes a mounting frame 3-2, and the top two sides of the mounting frame 3-2 are respectively connected to the bottom side of the working platform 2 by telescopic slide rails 3-1. A screw conveyor 3-3 for conveying slurry is provided at the bottom of the mounting frame 3-2, and a stirring device is provided above the screw conveyor 3-3. The discharge port of the stirring device is correspondingly connected to the feed port of the screw conveyor 3-3 through a gate valve 3-4.

[0060] When grouting is required, the mounting frame 3-2 can be pulled out through the telescopic slide rail 3-1, and then the stirring device can be pulled out to stir the mortar. After the mortar is stirred, the gate valve 3-4 is opened to allow the mortar in the stirring device to flow into the screw conveyor 3-3. The outlet of the screw conveyor 3-3 is connected to the grouting hose to carry out the grouting operation. When the work platform 2 needs to be moved, the stirring device can be retracted to the bottom of the work platform 2 through the telescopic slide rail 3-1. As shown in the attached figure Figure 5 As shown, a side box which can be pulled out together with the stirring and grouting device 3 is connected to the work platform 2 corresponding to the stirring and grouting device 3, and tools or grouting hoses can be stored in the side box.

[0061] Combined with Figure 6 The stirring device comprises a box body 3-5 with an open top, and a stirring shaft 3-6 with stirring blades is rotatably connected to the bottom of the box body 3-5, and the stirring shaft 3-6 is arranged horizontally. This design can effectively reduce the overall height of the stirring device while ensuring the stirring efficiency, and is convenient for installation at the bottom of the working platform 2. A driving device 3-7 for driving the stirring shaft 3-6 is arranged outside the box body 3-5, and the driving device 3-7 can be an electric motor or a hydraulic motor.

[0062] In order to further reduce the overall height of the mixing device and prevent mortar from splashing during mixing, an anti-splash device is provided on the top of the box 3-5. Figure 7 and 8 As shown, the anti-splash device includes a frame 3-8 connected to the top of the box 3-5, two inclined baffles 3-9 are arranged at intervals on both sides of the frame 3-8, and an inverted V-shaped baffle 3-10 is arranged in the middle of the frame 3-8, and the bottom edge of the inverted V-shaped baffle 3-10 extends between the two upper and lower inclined baffles 3-9 on the corresponding side. The purpose of anti-splash is achieved by the staggered arrangement of the inverted V-shaped baffle 3-10 and the inclined baffle 3-9, thereby preventing the mortar from splashing while reducing the height of the box 3-5. At the same time, there is no need to remove the anti-splash device when feeding into the box 3-5, which is convenient for operation.

[0063] The frame 3-8 is correspondingly plugged into the top of the box 3-5, and a limit retaining edge 3-11 is provided outside the frame 3-8, that is, the frame 3-8 is detachably connected to the top of the box 3-5. The operator can regularly remove the anti-splash device and clean the mortar adhered to the anti-splash device.

[0064] In order to further improve the uniformity of the mortar, a vibrator 3-12 is provided at the bottom of the box 3-5. During the mixing operation, the vibrator 3-12 can be turned on to improve the uniformity of the mortar and improve the mixing efficiency.

[0065] A screen is provided on the top of the stirring device to prevent large particles or foreign matter from entering the stirring device, thereby avoiding accidental blockage of the gate valve 3-4 or the screw conveyor 3-3 during the grouting operation.

[0066] The structure and working principle of the adaptive gripper 6:

[0067] As attached Figure 1 , 9As shown in 10, the boom system 5 is installed on the top of the working platform 2, and a hydraulic station is also provided on the top of the working platform 2 to provide a power source for the boom system 5 and the hydraulic legs 4. If the driving device 3-7 of the stirring grouting device 3 is a hydraulic motor, the hydraulic motor also obtains the power source through the hydraulic station. The working end of the telescopic arm of the boom system 5 is detachably connected with an adaptive clamp 6, which includes a fixed seat 6-1, and a group of clamps are provided at both ends of the fixed seat 6-1. A cavity is provided at the bottom of the fixed seat 6-1, and a telescopic cylinder 6-2 for driving the two sets of clamps to open or close is provided in the cavity. The telescopic cylinder 6-2 is arranged in the cavity at the bottom of the fixed seat 6-1 to avoid interference with the movement of the telescopic cylinder 6-2 by other components.

[0068] The clamp comprises two U-shaped clamp arms 6-5 symmetrically arranged on both sides of the fixing seat 6-1, and one end of the two U-shaped clamp arms 6-5 is correspondingly rotatably connected to the fixing seat 6-1. Fig. 9 As shown, the clamping head end of the U-shaped clamping arm 6-5 is not coaxial with the rod of the U-shaped clamping arm 6-5. When the U-shaped clamping arm 6-5 rotates along its rod, it drives the clamping head end to move toward the center to achieve a clamping action or to expand outward to achieve an opening action. A rubber sleeve 6-12 is provided at one end of the U-shaped clamping arm 6-5 corresponding to the top of the fixing seat 6-1, which can effectively prevent the U-shaped clamping arm 6-5 from clamping and damaging the clamped object.

[0069] Both ends of the telescopic cylinder 6-2 are connected to the corresponding clamps through a fork-shaped connection mechanism. The fork-shaped connection mechanism includes a guide slot 6-9 provided at the bottom of the fixed seat 6-1, and a slider 6-3 that slides in correspondence with the guide slot 6-9. The U-shaped clamp arm 6-5 is fastened with a connecting rod 6-4 at one end corresponding to the bottom of the fixed seat 6-1. The two connecting rods 6-4 of the same clamp are correspondingly crossed and staggered up and down, and the connecting rod 6-4 is provided with a strip slot 6-10. The slider 6-3 is provided with a guide rod 6-6 that movably passes through the strip slot 6-10, and the end of the guide rod 6-6 that is away from the slider 6-3 is connected to the telescopic cylinder 6-2. That is, the telescopic cylinder 6-2 can drive the guide rod 6-6, and the guide rod 6-6 drives the slider 6-3 to move along the guide slot 6-9. During the movement of the guide rod 6-6, the connecting rod 6-4 is driven to deflect, and the connecting rod 6-4 drives the U-shaped clamp arm 6-5 to rotate, thereby achieving the purpose of driving the clamp to open or close. As shown in the attached Fig.10 As shown, the clamp opens when the telescopic cylinder 6-2 is shortened, and the clamp closes when the telescopic cylinder 6-2 is extended.

[0070] It should be noted that when clamping an irregular object by two sets of clamps, when one set of clamps has clamped the object, the telescopic cylinder 6-2 can continue to extend so that the other set of clamps can also clamp the irregular object, thereby ensuring the reliability of clamping.

[0071] Embodiment 2, in combination with Figure 3 , 5And 11, an arch anchor injection combined operation trolley, which is different from Example 1 in that, on the basis of Example 1, the working platform 2 and the support plate 1-3 are provided with correspondingly overlapped pin holes, and the limit pins 1-12 are movably inserted in the pin holes, that is, during the process of transporting the working platform 2, the limit pins 1-12 can limit the slip of the working platform 2 to avoid the misalignment of the working platform 2 and the trailer body 1.

[0072] Embodiment 3, in combination with Figure 2 and 4 , an arch anchor grouting combined operation trolley, based on embodiment 1 or 2, a cover plate 1-13 is detachably connected to the support plate 1-3 corresponding to its clearance notch.
